Do you mean $a instead of $s? Either way is the same though assuming
$s is empty too.

No. Should be 1. You have forgotten about the newline at the end of
the command. The echo will terminate with a newline. You can see
this with od.
echo | od -tx1 -c
0000000 0a

Since this appears to be a usage error I have closed the bug. Please
feel free to follow up with more information. We will read it. And
we appreciate additional communication! I am simply closing it to
keep the accounting straight. :-)
